IP multicast routing failed (missing OS route)

Hllrdm — Wed, 19 Oct 2022 05:08:39 GMT

We have encountered a problem that our wifi router sends a lot of packets to the address (239.255.255.250) with IP multicast routing failed (missing OS route).
I read in sk that you need to configure the pim/igmp interfaces.
I configured the pim and igmp interfaces but wifi does not work and we still see drops.

Can IP multicast routing failed (missing OS route) cause my wifi to not work? How can we fix it?

Better open a SR# with TAC to get this resolved !
